Application filed October 3, 1914. Serial No. 864,832.

To all whom it may concern Be it known that 1. (.un. A. SHELLBERG, a citizen of the United States, residing at Elgin. in the county of Kane and State of Illinois, have invented new and useful Iniprovements in Ball-Bearings, of which the following is a specification.

This invention relates to bearings and more particularly to shaft hearings.

In bearings of this character. as well as in axle bearings, it is frequently found that the bearings will bind on the shafting or axle owing to the fact that the boxes are not in true angular relation with the shaft or axle either vertically or horizontally.

Itis the object of this invention therefore to avoid this ditticulty and broadly speaking, consists in providing novel means for adjusting the relation of the bearing to the box so as to secure the same against rotation without binding.

Further objects of the invention will appear as the following description is read in connection with the accompanying drawing which forms a part of this application, and in which:

Figure 1 is a sectional view taken through a. line shaft and showing the bearing in side elevation. Fig. 2 is a vertical section on the line 2.2 of Fig. 1.- transvcrsc sectional view taken approximately on the line 3-3 (if-Fig. 2. Fig. 4 is a side elevation of a cup holder. Fig. 5 is an enlarged sectional view therethrough.

Fig. 6 is a detail sectional view of the cone employed. Fig. '4 1s a sectional vlew showing the application of the invention to a car axle.

Referring to the drawings and more particularly to Fig. 1. 1 represents an ordinary pillow block and 2 the cap therefor which is secured to the block in the usual manner by the lag screws 3. The block and cap are both hollowed out as shown at 4 and 5 to receive the cup holder generally indicated at 6. This cup holder is in the nature of a sleeve having a split 7 and a convex outer face 8 adapted to tit within the concavities 4 and 5 in the block and cap 1 and 2. The bore of the cup holder is internally threaded from either side as shown at 9 and 10 and is provided with an annular channel 11 intermediate the threaded portions whichniay be employed for receiving a suitable lubricant if desired. Threaded into the portions Fig. 3 is a vertical,

Sand 10 are suitable cups 12 and 13 which are held firmly in adjusted position within the cup holder when the cap 2 is clamped upon the pillow block by the lag screws 3. These cups have suitable ball races l-i in which the anti-friction balls 15 are ar-,

ranged, the construction being such that'the balls have a three point bearing, although it will be clearly understood that they may be constructed to have only a two point or a single point. hearing as may be found desirable. The-balls are retained in position within the ball-race by a retaining ring 16, and bear directly against the cone 1? which is keyed to thelaxl or shaft 18 and held against longitudinal movement on said shaft by a set screw 15) passing through the cone between the inclined; ends thereof.

It will be seen from the foregoing. that as the cup member hits its outer convex face fitting the sockets -l iand in the nature oi a hall and socket jo'jzat. that the position of, the box relative. tot the alineiuent ot the shaft is immaterial to a certain degree as the cup holder will turn within the sockets freely and thereby prevent binding of the shaft within the hearing as would he the case where the shat' or axle fitted a bushing secured tightly u the box. It will be seen that when the pap :2 is clamped upon the pillow block 1 tliat owing to the split 7 in one side of the cuf' p-holder, that the same will be retracted upon the cups 12 and 13 and they will be htld firmly in adjusted position until readiiustment is necessary which is effected by releasing the cap 52 and applying a spanner or other similar wrench to the notches 20 formed in the outer face of the cup. I

In the structure shown in Fig. 7, an ordinary car axle 21 has secured thereon a sleeve 2:2 provided with annular ribs 23 having inclined faces :Z-L for the abutment oi the antifriction balls 26 which are carried in cups 27 similar to the cups l2 and 13 formerly described. The cups are held in a cup container 28 constructed similarly to the container G and adapted to tit a bearing box secured in any suitable manner upon the truck and which is constructed similarly to the box disclosed in Figs. 1 to 3. in this instance. the sleeve 22 is held against rotation, upon the axle by keys 29 and against longituiiliual movement on the axle by a plated-30 which abuts the end of the sleeve Patented June :31 355155.
